Definitions

  • the present invention relates to the manufacture of multiple glazing with joints made of organic materials and more particularly the pumping and distribution of these organic materials with a view to providing a continuous bead intended to serve as a joint and interlayer between two consecutive glass sheets of multiple glazing.
  • the extrusion machine is a heavy and fairly powerful machine, and consequently quite expensive; this is due to the high performances which are required for correct extrusion which supposes an extrusion stop at each corner of the glazing and each time a restart with an immediately constant flow rate.
  • the space between two consecutive sheets of glass of multiple glazing or in other words the thickness of the gas plate, in general of air, enclosed depends directly on the thickness and the regularity of thickness of the bead arranged between said two sheets of glass, also given that the insulation performance of multiple glazing, its ability to remain perfectly transparent, without fogging between the sheets of glass depends on the tightness of the joints between the sheets of glass and in particular of the tightness and regularity of the bead in the butyl rubber type, it is important to ensure the perfect quality of the bead forming a joint and interlayer if we want well-calibrated glazing with good performance. Furthermore, with thick intermediate air knives, the flow rate supplied by the pump may be temporarily insufficient, even though its average flow rate is itself greater than the theoretical flow rate required.
  • the present invention aims to allow the supply of a bead of organic material of the type based on butyl rubber, or more generally a bead of a material with high viscosity, with at least all the advantages and performances of the preceding installations, without, however, the drawbacks of said installations.
  • the airlock makes it possible to maintain a certain quantity of material available, already under pressure, near the outlet nozzle, so that this material is immediately available as soon as necessary.
  • the pressure of the material in this airlock is regulated.
  • pressure regulation is obtained by means of a pressure regulator assembly essentially consisting of an accumulator / compensator connected in bypass to the airlock, formed of a chamber closed by a piston controlled as a function of the pressure displayed by a pressure gauge.
  • a pressure regulator assembly essentially consisting of an accumulator / compensator connected in bypass to the airlock, formed of a chamber closed by a piston controlled as a function of the pressure displayed by a pressure gauge.
  • This embodiment is improved by regulating the pressure of the material supplied by the reciprocating pump, which is obtained, for example, by providing a second accumulator / compensator assembly, located bypassing the pipeline upstream of the airlock.
  • this first embodiment has the disadvantage of operating correctly only if there is accumulation chamber whose volume is sufficient to store the quantity of material necessary for a given glazing, which supposes cylinders dimensioned accordingly, and particularly substantial hydraulic powers.
  • the pressure in the airlock is regulated not by a regulator assembly mounted in bypass but by complete regulation of the flow rate supplied to the inlet of the airlock.
  • the airlock is supplied by an extrusion chamber closed by a piston preferably controlled by two pistons actuated by a constant flow pump.
  • the reciprocating pump mounted on the barrel is then used only for feeding the extrusion chamber, the flow - and the pressure - of material necessary for extrusion being ensured directly by the piston of the extrusion chamber.
  • the reciprocating pump only delivers when the airlock is closed, that is to say when the nozzle is in the standby position.
  • the volume of the extrusion chamber is sufficient to produce several volumes without using the reciprocating pump on the barrel, this for example to allow the replacement of a barrel without interrupting production.
  • the supply circuit of the extrusion nozzle comprises not one but two extrusion chambers in parallel, each chamber being closed at its end opposite to the alternative pump by a valve acting in turn as a valve. entrance to the airlock.
  • one extrusion chamber can be filled by the reciprocating pump while the other chamber simultaneously supplies the airlock, which ultimately allows very high flow rates.
  • the invention also provides an installation providing a bead of organic material of the butyl rubber type, and in general of organic material with a high viscosity greater than 35,000 poises, installation which includes an alternative pump associated with a conical heating piston pressing on the organic material contained in a barrel, a pipe leading from the pump outlet to an outlet nozzle and which is equipped, near the outlet nozzle, with a portion of pipe limited by two valves and forming an airlock, provided with a pressure regulating system .
  • the installation according to the invention is particularly appreciated for manufacturing a bead of organic material of the butyl rubber type intended to enter into the composition of a multiple glazing with organic joints of the type of that shown schematically in the figure and marketed by the applicant under the brand "BIVER".
  • Such multiple glazing for example double glazing, consists of two glass plates 1 and 2 assembled at a certain distance from each other by means of seals 3 and 4 made of organic materials which also act as spacers or spacers glass plates 1 and 2.
  • the first seal 3 is made of a material of the butyl rubber type further comprising various ingredients which give it particular properties: - a certain mechanical strength, - a certain elasticity, - some tights, - an ability to absorb water vapor and various other effluents, - etc ...,
  • compositions of the organic material of this joint 3 are given by way of example in the French patent documents published under the numbers 2294314 and 2294313.
  • This seal 3 is deposited in the form of a continuous bead calibrated on the periphery of a glass plate, for example the plate 1; the two ends of this cord are then joined so as to constitute a complete belt, then a second glass plate is applied to this cord, thus enclosing an air gap between the two glass plates 1 and 2 and the joint 3 in cord .
  • this bead 3 which alone acts as a spacer for the two glass plates during the first phase of the production of multiple glazing, that is to say before the installation of the second seal 4 and above all it is which determines the height of the enclosed air space.
  • the bead which forms the joint 3, deposited on a glass plate during the manufacture of multiple glazing has a shape, and in particular a height, well defined to guarantee a thickness correct the enclosed air space and therefore the overall thickness of the multiple glazing, and that it also has perfect regularity of shape and more particularly of height over its entire length so that the glass plates 1 and 2 support identically along their entire periphery on the bead 3 thus ensuring a flawless seal over the entire periphery.
  • This seal 3 in the form of a bead being deposited, a second glass plate being put in place, a second seal 4 is poured, injected and generally put in place whatever the means used, in the groove formed by the edges of the two glass plates 1 and 2 and having the bead seal 3 as a background, over the entire periphery of the glazing.
  • This second seal 4 after possible polymerization, participates with the first seal 3 in sealing the glazing and in maintaining the glass plates, assembled and spaced at the distance defined by the seal 3.
  • This seal 4 can be made of polysulfide, in polyurethane, etc ...
  • the installation shown in FIG. 2 aims to obtain this regularity, and simultaneously aims to provide sufficient flow in order to manufacture large glazings, with a thick air gap, the amount of material forming the joint 3 in front in this case. be supplied in large quantities without any interruption and with the regularity mentioned above under penalty of the risk of poor quality of the glazing.
  • a possible poor quality of the glazing can result in the entry of water vapor inside said glazing, then, under certain temperature conditions, by the condensation of this water vapor and its deposition in the form of droplets of mist on the inner faces of the glass plates 1 and / or 2, droplets impossible to wipe due to their location inside the glazing.
  • This condensation prevents clear vision through the glazing on the one hand, and it reduces the insulation properties of said glazing.
  • the glazing in a construction are planned for a long lifespan - they are also covered by the ten-year guarantee in the same way as the shell - it is important that the quality of the gasket 3 in cord, which largely conditions the quality of the entire glazing , is perfect, on pain of seeing the faults previously mentioned appear if not immediately, at least after several years of service.
  • FIG. 2 makes it possible to obtain this quality and this performance and this for a reduced material cost, also reduced maintenance and assistance and excellent reliability.
  • This installation comprises an assembly 5 for pumping the raw material into a barrel 6, an assembly essentially comprising a conical heating plate mounted on the barrel 6 and pressed against the organic material contained in said barrel, an alternative double-acting pump 8 pumping the material organic in the conical end of the plate 7 and delivering it, at its outlet end 9.
  • the conical heating plate 7, the alternative pump 8 and their combination are described in the patent documents published in EUROPE under the numbers 171309, 238380 already cited, and reference should be made to it for further details.
  • the pump 8 is actuated by its jack 10.
  • the pipe 11 is advantageously flexible over the majority of its length. It is for example connected as described in the patent document published in EUROPE under the number 251929.
  • This installation also includes a compression / decompression system 13 mounted immediately upstream of the nozzle 12 and making it possible to obtain an immediate stop or restart of the supply of cord 3 when desired, for example when after having deposited cord 3 the along one side of a glass plate, we stop the supply of the bead at the corner of the glass plate, without however cutting said bead, and turning said glass plate, or the nozzle with respect to said glass plate, so as to continue laying the bead 3 along the next side.
  • a compression / decompression system 13 is described, as well as its mode of operation, in the French patent document published under the number FR-2207799.
  • the installation can also be equipped, completely at its end, outside of the nozzle 12, with a cord cutting blade 14 animated by a jack not shown and responsible for cutting the cord 3 when said cord has been delivered over the entire periphery of a glazing.
  • a cord cutting blade 14 animated by a jack not shown and responsible for cutting the cord 3 when said cord has been delivered over the entire periphery of a glazing.
  • this installation also includes, near the nozzle 12, on the pipe 11, an airlock 15 limited by two valves, an upstream valve 16 and a downstream valve 17, formed of a portion of pipe 18 equipped with a regulator 19 of the pressure of the organic matter in said portion 18 of pipe.
  • This pressure regulator 19 comprises, bypassing the portion 18 of the pipeline, an accumulator / compensator, that is to say a chamber 20 in which a piston 21 moves, under the action of a jack 22, for example pneumatic. , controlled by a pressure gauge 23 with a pressure threshold displayed, at the passage of which the jack 22 is actuated or stopped.
  • valves 16 and 17 are advantageously motorized by high-torque hydraulic rotary actuator, at least for the nozzle 16 located on the side where the pressure is highest, possibly with a simple linear cylinder for valve 17. These cylinders are not shown in the figures.
  • the position of the accumulator / compensator along the length of the portion 18 of the pipeline is adjustable; this accumulator / compensator is for example mounted on the branch connected substantially in the middle of the portion of pipeline 18.
  • the length of the portion 18 also influences the quality of the results; the optimal length is defined according to the working pressures, the nature of the organic matter, etc.
  • the portion lengths 18 are of the order of 40 cm to 1 m and for example 50 cm or 60 cm.
  • a second assembly 25 for regulating the pressure is installed at the outlet of the pump 8, at the inlet of the pipe 11.
  • This assembly 25 is essentially composed of a pressure accumulator / compensator, namely a cylinder 26 in which a piston 27 moves under the effect of a jack 28, for example pneumatic, controlled according to the indications of a pressure gauge 29 having two displayed pressure threshold values.
  • the installation operates as described below: a barrel 6 of organic material constituting the seal 3 of multiple glazing, in particular a material based on butyl rubber is supplied.
  • the pumping assembly 5 is mounted on the barrel 6.
  • the conical heating plate 7 of this assembly 5 is pressed against the material contained in the barrel 6.
  • the pumped material is supplied through the outlet 9 with a satisfactory flow rate, having a certain regularity, however insufficient for the application envisaged due essentially to the change of direction of the piston of the pump 8.
  • the operation of the pump 8 is adjusted to supply at outlet 9, a certain pressure, for example of the order of 350 bars, this so as to have at the outlet of the installation, at the outlet of the nozzle 12, an organic matter pressure acceptable for the envisaged application.
  • This pressure is a function in particular of the relative speed of movement of the glass plates with respect to the nozzle 12 when the gasket 3 in the bead is deposited on said glass plates, in the necessary bead height, etc., and it is for example of the order of 150 bars for running speeds of the glass of the order of about thirty cm / s.
  • the two valves 16 and 17 are open, the material passes through the airlock 15 and exits through the nozzle 12.
  • the pressure gauge 23 adjusted for a given threshold value controls the actuation in one direction or the other. of the jack 22, which triggers either the filling of the chamber 20 with organic material from the portion 18 of the pipeline, or the emptying of the chamber 20 and the discharge of the material into the portion 18 of the pipeline. More precisely when the pressure recorded by the threshold pressure gauge 23 is greater than the displayed threshold value which corresponds to the desired pressure in the circuit at this location, for example 150 bars, a resistance pressure, relatively low, only capable of prevent too sudden rise of the piston 21, is applied by the cylinder 22 on said piston. This results in the filling of the chamber 20, and a drop in pressure in the portion 18 of the pipeline, drop in pressure recorded by the pressure gauge 23. When this pressure drops below the threshold value, this controls the application of higher pressure on the actuator 22 and this causes the emptying of the chamber 20 and the injection of the organic material stored in the chamber 20 in the portion 18 of the pipeline.
  • the assembly 25 comprising a pressure gauge 29 with two thresholds.
  • the stopping of the pump 8 is controlled, as well as the application to the piston 27 by the jack 28 of a relatively low resistant pressure, sufficient however to prevent the sudden rise of said piston.
  • the cylinder 26 is filled with material until the pressure gauge 29 registers the drop in pressure below its low threshold. Immediately the pump 8 is restarted and a higher pressure is applied to the piston 27 by the jack 28, pressure which results in the emptying of the cylinder 26.
  • the material pressure is regulated to the displayed threshold pressure, for example 150 bars.
  • this regulated airlock 15 will be associated with an additional regulator 25 which will carry out a first smoothing.
  • FIG. 3 illustrates the second embodiment of the invention.

  • the material is led by a pipe 36 of the flexible type heating to an extrusion chamber 37, closed at its upstream end by a heated piston 38 whose displacements are controlled by two symmetrical hydraulic cylinders 39, actuated by a hydraulic pump here not shown.
  • the downstream end of the chamber 37 is closed by a valve 40 which, by cooperating with a second valve 41, delimits an airlock 42.
  • This airlock 42 feeds the extrusion assembly proper which notably includes a nozzle 43 and a compression system / decompression 44 similar to the system 13 visible in FIG. 2.
  • the nozzle 43 is here positioned above a sheet of glass 45, shown here during rotation thanks to a pivoting arm 47 on which it is immobilized by a or several suction cups 46 brought into contact with the glass when an angle is produced.

  • the reciprocating pump 34 is started so that the extrusion chamber 37 is force-fed. This force-feeding causes the rods of the pistons 39 to move back.
  • the pump 34 is stopped.

  • the pressure is for example equal to 200 bars whereas, owing to the pressure losses and above all the flow of the material through the outlet nozzle 43, the pressure is generally less than 150 bars at the level of valve 41.
  • the effective pressures depend on the pressure exerted on the jacks 39 on the one hand, and on the section of the outlet nozzle on the other hand.
  • the feeding of the extrusion chamber 37 is preferably carried out between two glazing units, closed valves 40 and 41 and stopped hydraulic pumps.

  • each extrusion chamber is closed by a valve, the valve of the "active" chamber, that is to say from which the extrusion takes place, constituting the airlock inlet valve.
  • Such a circuit has the advantage of allowing almost permanent operation of the pump mounted on the barrel which can supply the inactive chamber without disturbing the operation of the assembly.
  • This embodiment is particularly useful for installations where the extrusion nozzle delivers practically continuously and / or installations where the flow rate supplied by the vane pump is relatively low, which is for example the case with very "hard” butyl rubbers, chosen as a function of very good resistance to compression, by example of butyl rubbers whose viscosity expressed in MOONEY degrees is greater than 120 °, after eight minutes at 40 ° C (measurement carried out with a MOONEY consistometer according to the ASTM D recommendation 1646-74), by additionally imposing a temperature of the rubber during its extrusion by the nozzle less than 100 ° C.
  • Such perfectly regular strands of organic material can also be used in fields other than multiple glazing, in particular in the automotive field for providing seals, etc.
